Suspend to RAM

[Peter Carlsson <maillist.peter@home.se>]

Hello!

I'm trying to get suspend to RAM working on my Gigabyte
GA-K8N51PVMT-9 running Debian (testing).

What I initially want to manage is to have the system
suspend and then wake up on a specific date/time.

I was thinking that the suspend was done by:

- Create a file /etc/acpi/events/suspend containing:
event=suspend
action=/etc/acpi/suspend.sh

The /etc/acpi/suspend.sh will contain necessary actions
to unload modules etcetera and the following line:

echo '2006-07-05 20:27:00' > /proc/acpi/alarm

The wake up will then take place when the date/time is.

What else is necessary for the wake up?

Is it possible to trigger an event with for example:

echo 'suspend' > /proc/acpi/event

I can't get this to work which makes me feel I am wrong
with my understanding of how ACPI works. Any help or
information would be greatly appreciated.

Below are some information that might be helpful.
